LAfet® wire feed device

Process safety and the greatest reproducibility of laser welding with optimized welding time.

Laserdrahtvorschub LAfet Duplex

LAfet®-SM Duplex laser wire feed system

Automatic feed for slip-free conveying of welding wires 0.3 mm to 1.2 mm in diameter. The wire feed system can be used in both pulsed laser welding processes and in CW mode.

  • Secure wire transport by two power-driven, extremely fine-toothed carbide gears.
  • Planetary transmission for highest torque.
  • Pinch roller fine adjustment for defined groove profile on wire surface.

With the adjusting frame, the wire axes of the drive’s “internal capillary tube” can be set to the welding filler diameter.

The drive unit can be attached as you choose:

• to the laser head with two hydraulic clamping arms and XYZ fine adjustment for direct feed, or
flexibly using a guide spiral and separately adjustable capillary tube positioning on the focusing lens.

The control logic allows precise adjustment to the laser welding process.
Variable speeds ensure precisely timed wire movement at the beginning, during and at the end of each weld.
